Discontinued Legacy Addons for Firefox

Firefox Quantum has been released a few days ago. The new update from Mozilla is one met with excitement from many users, for good reason. Firefox Quantum is extremely fast, gives you a smooth browsing experience, comes with a polished interface, and finally drops Small Yahoo! Search iconYahoo! Search as the default search engine (Sorry Yahoo, it was time for you to go). There were, however, many users who were frustrated with the new update, as many of the add-ons that made Firefox so useful are no longer supported in the Quantum update.

Firefox Quantum uses the new WebExtensions API, while many add-ons use the older API that is no longer supported in the updated version. This comes as a disappointment, especially for power-users who enjoyed Firefox for the powerful add-ons that were created for it, such as Small Firebug iconFirebug or Small FlashGot iconFlashGot . So if you're one of the users that is unhappy about the lack of backwards compatibility, what can you do?

First, you can search for an alternative extension. Luckily, Firefox makes this pretty easy. If you go into "Add-Ons" from the Firefox menu, you'll see your current add-ons. If you aren't seeing add-ons that you previously had installed, before the update, then it is likely they aren't supported in the new version. If this is the case, you can find them by clicking "Legacy Extensions" on the left-hand side of the page. You should see something similar to the screenshot below (depending on the add-ons installed, of course):

Firefox Add-On Settings

As you can see, if you have an unsupported legacy add-on installed, Firefox now gives you the ability to "Find a Replacement." Which you can do by clicking the respective button, on the right-hand side of the add-on. From there, you'll be taken to a page where you can browse alternative add-ons for the unsupported legacy add-on. In most cases, for most add-ons, this works well and you are likely to be able to find a suitable replacement for the add-on you were attached to.

Second option, you can wait and hope that the developers port the legacy add-on to the new WebExtensions API. Unfortunately, some add-on developers have already announced that they won't be porting to support WebExtensions API, such as Small Firebug iconFirebug and Small Selenium IDE iconSelenium IDE . Others have announced that updates are in the works, such as Small LastPass iconLastPass and Small Greasemonkey iconGreasemonkey , so be sure to check out the website for your favorite add-on to see what the status on an update is.

Finally, if the above two options don't work for you, you can always find and switch to an alternative web browser. You can check out the possible alternatives to Small Mozilla Firefox iconMozilla Firefox . But before you think about making the switch to another browser, you should know that Firefox Quantum is an incredible leap forward for Firefox. The improvements are tremendous, and Mozilla's commitment to ensuring future stability with the browser is clear - you may want to stick around with Firefox.

Here is a list of some of the top add-ons that will not be updated and therefore will not work in Firefox Quantum:


  • Download Status Bar

    Free Mac OS X Windows Linux Pale Moon Thunderbird ... SeaMonkey Firefox Website

    Download Status Bar manages every aspect of your downloads (Launch, Show, Scan, Send To, Rename, Checksum, Pause, Resume, Cancel, Clean, Delete), generates Statistics from your Download actions, keeps the History of your previous session downloads and much more. It is not only a download management add-on but a helper tool for boosting your Productivity, too.

  • Clean Uninstall

    Free Mac OS X Windows Linux Waterfox Pale Moon ... Firefox Website

    "Clean Uninstall" cleans fingerprints (such as preferences) left by an add-on from your Firefox profile upon its removal. Usually add-on developers do not clear preferences created by their extension just before extension gets uninstalled. This leads to have a massive pref.js file once you have tried a few extensions. So after trying out a few extensions, although you have removed them, but your Firefox is not as responsive as it used to be. This extension notifies you about these preferences after an extension got removed.

    Features

    No UI element is added to Firefox to prevent decluttering
    Allows you to remove extension's fingerprints
